Inspired by the 1930s three-strip technicolor process, this colour separation dance film was choreographed, performed, and printed by the artist. A red, green, and blue version of the dance were choreographed separately and filmed onto black and white 16mm film through their respective colour-separation filters. The three black and white films were then optically printed through their respective filters and superimposed onto colour film in order to recreate a full colour image in which the artist’s body alternately merges into natural colour and separates into additive and subtractive primaries. Through this process, the red, green, and blue choreographies generate cyan, magenta, and yellow figures. The gestures in this dance work explore the psychological fracturing and reunification in representations of the female body. 3part Harmony was edited in the optical printing camera, one frame at a time, in order to explore the superimposition of choreographic movements not possible in live performance. The result is a dance work inseparable from the materiality of film, and a film that is distinctly choreographic.
